openwrt-luci 使用 ddns

安装luci-app-ddns 后，服务中找不到，用脚本实现

vi /root/ddns

#!/bin/sh -
USER="xxxxx"
PASS="ppppp"
DOMAIN="ooooooooo.wicp.vip"
URL="http://${USER}:${PASS}@ddns.oray.com:80/ph/update?hostname=${DOMAIN}"

if [ -f /tmp/ddns_oray_res ]; then
    current_ip=$(ubus call network.interface.wan status | grep \"address\" | grep -oE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}';   )
    req=`cat /tmp/ddns_oray_res| grep "${current_ip}"`
    if [ ! -z "${req}" ]; then
        old_ip=`echo ${req}| awk '{ print $2}'`
        if [ "${old_ip}" = "${current_ip}" ]; then
            exit
        fi
    fi
fi

wget -q -O /tmp/ddns_oray_res -q ${URL} 

chmod a+x /root/ddns
crontab -e
